ABSTRACT:
In a method for the fabrication of nuclear fuel compacts, a cylindrical mold is filled with coated particles containing fissile and fertile material as well as grains of graphite if necessary. The mold is heated to a temperature above the softening temperature of pitch which is injected into the mold in the hot state through openings provided at regular intervals along the mold wall and having a diameter which is smaller than the size of the coated particles, the injection of pitch being carried out at right angles to the generator-lines of the cylinder formed by the mold.
